I would do a few things differently. I would stay longer and would include part of the stay as a solo trip then have my family join me. I would always stay in a deluxe - either AKL or Beach which I have stayed at before but generally do moderates due to the cost difference.
I would probably do the same as far as meals go since I enjoy my one sit down meal a day for a relaxing experience with good food but I also like the quick service for the speed and I'm not too fussy so I don't mind (and in fact frequently really enjoy) my favourite quick service locations.
...and I would shop. I would shop and shop and shop. I would either have a large empty suitcase or I would ship things home. I limit my shopping for myself at Disney World to - 1 ring, 1 pair of earrings, 1 purse, 1 book and 1 piece of art. Those are the kinds of things I have come to realize give me the most pleasure and I actually use and appreciate most when I get home but if money were no object there would be no limits.
I would have enough Christmas ornaments to decorate at least 3 trees. I would have a full line of sweats, T's and hoodies which I wear when I work from home. I would have some kitchen utensils that I always thought were cute but were never on my "must have" list. I would get more artwork that I've always admired but get wide-eyed at the price tags.
I assume if money were no object I'd be living in a larger house so it should be adequate to store all my Disney stuff.
